The Park Service holds evening ranger programs intermittently at Hole-in-the-Wall campground; they're worth planning a stop around. The programs might include talks on the endangered desert tortoise or the area's geological history, or an evening slide program. Guided walks to petroglyph sites are also offered. Contact one of the information centers for the current schedule.
